Abstract

An illumination assembly including a thermally conductive substrate, a reflective layer proximate a first major surface of the thermally conductive substrate, a patterned conductive layer positioned between the reflective layer and the first major surface of the thermally conductive substrate and electrically isolated from the thermally conductive substrate, and at least one LED including a post that is attached to the thermally conductive substrate is disclosed. The at least one LED can be thermally connected to the thermally conductive substrate through the post and electrically connected to the patterned conductive layer.
